    Looking for wiring diagram for gas furnace
    I Have an American Standard Gas Furnace model CDB080A945D0. Having problem with main Blower not starting after furnace fires up. I changed the control board but still have the problem. I checked seņors for continuity the only one Im not sure about is the Flame sensor. Does the Flame sensor contron the blower for starting? I did check to make sure I have 24v to the board for blower from the T-stat. That's good. I checked the blower motor also. I bypassed the board and power blower motor direct and the blower motor works. I am an A/C Heat guy but this has me stumped. I am missing something.

    If the blower motor has a capacitor, this is the first suspect.
